I found another bug related to this problem.
Nextcloud, qv2ray and so on, which is based on qt, not only can not show tray icons,but also, when I click on the taskbar of these applications, their interface display is very simple, which is different from the non-self-starting of these applications. It should be that qt is not called normally.
